Description

Technical Field

[0001] This invention belongs to the field of fruit planting technology, specifically a handheld fruit tree hole digger for fruit planting. Background Technology

[0002] With economic development and continuous improvement of technology, my country's fruit planting industry has developed very rapidly. When planting fruit trees, it is necessary to use hand-held fruit tree hole diggers to dig holes. Hand-held hole diggers, also known as portable hole diggers, are special machines for planting trees, fertilizing, and quickly digging holes in mountainous, hilly, and gully areas.

[0003] A handheld fruit tree posthole digger with publication number CN220733460U is currently available. After digging the hole, the drill bit moves upward using a threaded sleeve, eliminating the need for workers to lift the drill bit, thus reducing labor intensity and increasing digging efficiency, and greatly improving the practicality of the digger. However, during actual digging, soil spirals up along the outer surface of the drill bit, adhering to it and causing it to become dull. If soil viscosity increases due to factors such as rain, the drilling capacity of the drill bit will decrease significantly due to soil adhesion. Therefore, improvements are needed. Summary of the Invention

[0004] To address the problem of existing drill bits becoming dull due to soil adhesion, the present invention provides a handheld fruit tree planting hole digger, comprising a base component, a support plate, and a cleaning component. The cleaning component is symmetrically arranged on both sides of the upper surface of the support plate, and the support plate is disposed inside the base component. The cleaning components include an inner pressure shell, an outer drainage box, and an infusion tubing: The outer surface of the external drainage box is connected to the outer surface of the infusion tube through the infusion port, and the lower surface of the external drainage box is connected to the upper surface of the support plate. The inner pressure shell is fitted onto one side of the inner cavity of the support plate. A through-hole is provided in the middle of the inner cavity of the support plate. Spray pipes are evenly inserted into the outer surface of the inner pressure shell and extend into the inside of the through-hole of the support plate. The outer drainage box absorbs water through the infusion pipe and injects it into the inner pressure shell through the internal pump and the bottom connecting pipe. Then, the inner pressure shell pressurizes and sprays the water out through its spray pipes. The cleaning components on the left and right sides completely surround the through-hole in the middle of the support plate. When the spray pipes spray water synchronously, they can completely cover the through-hole of the inner pressure shell.

[0005] Furthermore, it also includes: The drilling platform components are mounted on the upper surface of the support plate; The anti-fall component is located at the axis of the base component.

[0006] Furthermore, the base component includes: The bottom frame has deflecting wheels evenly arranged on its lower surface. The deflecting wheels can rotate. The bottom frame has symmetrically opened insertion grooves on both sides of its inner cavity. Sliding connecting plates are symmetrically inserted into both sides of the bottom frame's inner cavity through the insertion grooves. The top of the sliding connecting plates is inserted into the lower surface of the supporting plate. Vibration-enhancing components are symmetrically arranged on the front and rear sides of the inner cavity of the bottom frame; A vertical connecting plate, the bottom of which is inserted into the outer surface of the base frame; The rear traction plate is inserted into the back of the vertical connecting plate at its front end. The operator moves the device by pulling the rear traction plate.

[0007] Furthermore, the fall protection component includes: A strip-shaped sliding box, wherein air drainage grooves are symmetrically provided on the upper and lower sides of the inner cavity of the strip-shaped sliding box, and the outer surface of the strip-shaped sliding box is slidably connected to the axis of the inner cavity of the vertical connecting plate; The height-limiting arc plate has its back end inserted into the front end of the strip-shaped sliding box, and the front end of the height-limiting arc plate is evenly provided with drying air holes. The bottom end of the height-limiting arc plate is in contact with the upper surface of the supporting plate. The inner cavity of the height-limiting arc plate is a hollow structure, and both the upper and lower ends of the height-limiting arc plate are reinforced by welding metal plates. The rear pressure control plate has its outer surface inserted into the back of the outer surface of the vertical connecting plate. The front of the rear pressure control plate is uniformly provided with compression push tubes. The front end of the compression push tubes is inserted into the back of the strip-shaped slide box. After the rear pressure control plate pressurizes the inside of the compression push tubes, the compression push tubes extend and push the strip-shaped slide box forward. Then, the air duct of the strip-shaped slide box is exposed to the outside of the vertical connecting plate, and it begins to adsorb air and perform heating. Therefore, the drying air that is finally sprayed from the front of the height limiting arc plate is heated air. Furthermore, the vibration-enhancing component includes: A hollow guide tube, the outer surface of which is evenly arranged in the inner cavity of the base frame through an insertion interface; A solid slide rod, wherein a compression spring is sleeved on the outer surface of the solid slide rod, the top end of the solid slide rod is inserted into the lower surface of the support plate, and the bottom end of the solid slide rod is slidably connected to the inner wall of the hollow guide cylinder; The variable frequency pump plate has its top connected to the bottom of the hollow guide cylinder via an insertion interface, and the upper surface of the variable frequency pump plate housing is connected to the lower surface of the base frame. The variable frequency pump plate can change the pressurization and depressurization of the hollow guide cylinder cavity by rapidly changing the internal air pump, so that the solid slide rod can perform vertical sliding variable frequency movement, thereby driving the support plate to slide up and down.

[0008] Furthermore, the drill rig components include: The upper sliding plate has a guide opening in the middle of its inner cavity; A torque motor is provided, wherein the outer surface of the torque motor housing is inserted into the upper surface of the upper slide plate, a solid drill rod is inserted into the outer surface of the torque motor shaft, and a helical blade is sleeved on the outer surface of the solid drill rod, and the outer surface of the torque motor shaft is rotatably connected to the inner cavity of the guide port of the upper slide plate.

[0009] Furthermore, the drill rig component also includes: The motor is fitted with a long threaded rod inserted into the outer surface of the motor shaft. The guide bottom cylinder has its bottom end rotatably connected to the inner wall of the guide bottom cylinder, and a rangefinder is installed in the inner cavity of the guide bottom cylinder. The protective cylinder shell has its bottom end inserted into the upper surface of the support plate, the bottom of the guide bottom cylinder inserted into the bottom of the inner wall of the protective cylinder shell, and the top of the cooperating motor snapped into the top of the inner wall of the protective cylinder shell. A connector, one side of which is sleeved on the outer surface of a long threaded rod, and the other side of which is sleeved on the inner cavity of an upper sliding plate.

[0010] Furthermore, the connector includes: A horizontal connecting plate, the outer surface of which extends to the outside of the protective shell, and the outer surface of the horizontal connecting plate is slidably connected to the inner cavity of the protective shell through a sliding groove. An anchoring rod, the top of which is inserted into the end of the horizontal connecting plate away from the protective shell, and the outer surface of which is inserted into the inner cavity of the upper sliding plate through an insertion interface.

[0011] Furthermore, the connector also includes: A threaded rotating sleeve, wherein the inner wall of the threaded rotating sleeve is threadedly connected to the outer surface of a long threaded rod through a threaded groove; The adapter collar has its inner wall fitted into the middle of the outer surface of the threaded sleeve. The lower surface of the adapter collar is uniformly provided with photosensitive interfaces. The outer surface of the adapter collar is rotatably connected to the end of the horizontal connecting plate away from the anchoring rod through a rotating groove. The infrared rays emitted by the guide bottom cylinder inside the guide bottom cylinder can be received by the photosensitive interface of the upper adapter collar, thereby feeding back to the mating motor. The rotation speed of the mating motor is adjusted according to the distance between the two.

[0012] The beneficial effects of this invention are as follows: 1. This device can, without affecting the drilling operation, use the inner pressure shells on both sides to flush the outer surface of the solid drill rod and the spiral blades with water after each drilling operation. This removes the mud and impurities adhering to the outer surface of the drill rod, preventing the drill bit from becoming dull and difficult to drill due to excessive mud. Furthermore, when the solid drill rod is idle, the fitting height-limiting arc plate dries the outer surface of the solid drill rod and the spiral blades, eliminating water stains and preventing oxidation.

[0013] 2. The solid drill rod and spiral blades used for drilling are relatively heavy. Therefore, in standby mode, due to the support of the height-limiting arc plate, the entire upper slide plate will not suddenly fall to the ground due to gravity. This distributes most of the gravity load to the surrounding connecting parts, thus avoiding the problem of deformation failure of the connecting parts due to long-term load-bearing. It also avoids the problem of the drill platform components suddenly falling and damaging the ground, eliminating safety hazards.

[0014] 3. During the retraction of the solid drill rod, the variable frequency pump plates located on both sides of the bottom frame drive the solid slide rod to slide up and down through pressure control. This causes the solid slide rod to push the support plate and drill platform components to vibrate up and down, shaking off large pieces of soil from the gap between the solid drill rod and the spiral blades. This ensures that the impurities washed away by the inner pressure shell are uniformly small pieces of soil. On the one hand, this ensures effective washing, and on the other hand, it avoids the problem of long washing time for large pieces of soil, which would affect the actual drilling efficiency of the drill rod.

[0015] 4. During the downward movement of the adapter collar, the adapter collar monitors the advancing distance by receiving infrared light from the lower guide cylinder. This stops the movement when the upper slide plate is about to approach the outer drainage box, preventing the heavier upper slide plate from pressing on the upper surface of the outer drainage box and crushing or damaging it. It also prevents the threaded sleeve from being screwed to the bottom of the long threaded rod and locking with it, which would make it difficult to rescrew the threaded sleeve and reset the upper slide plate.

Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0019] Example 1, please refer to Figures 1-4 This invention provides a technical solution: a handheld fruit tree planting hole digger, comprising a base component 1, a support plate 4, and a cleaning component 5. The cleaning component 5 is symmetrically arranged on both sides of the upper surface of the support plate 4, and the support plate 4 is disposed inside the base component 1. Cleaning component 5 includes an inner pressure housing 51, an outer drainage box 53, and an infusion tubing 54. The outer surface of the external drainage box 53 is inserted into the outer surface of the infusion tube 54 through the infusion port, and the lower surface of the external drainage box 53 is inserted into the upper surface of the support plate 4. The inner pressure shell 51 is fitted onto one side of the inner cavity of the support plate 4. A through-hole is provided in the middle of the inner cavity of the support plate 4. Spray pipes 52 are evenly inserted into the outer surface of the inner pressure shell 51, and the spray pipes 52 extend into the inside of the through-hole of the support plate 4. The outer drainage box 53 absorbs water through the infusion pipe 54 and injects it into the inner pressure shell 51 through the internal pump body and the bottom connecting pipe. Then, the inner pressure shell 51 pressurizes and sprays the water out through its spray pipes 52. The cleaning components 5 on the left and right sides completely surround the through-hole in the middle of the support plate 4. When the spray pipes 52 spray water synchronously, they can completely cover the through-hole of the inner pressure shell 51.

[0020] Also includes: Drilling platform component 3 is disposed on the upper surface of support plate 4; The anti-fall component 2 is located at the axis of the base component 1.

[0021] Base component 1 includes: The bottom frame 13 has deflection wheels 14 evenly arranged on its lower surface. The deflection wheels 14 can rotate. The bottom frame 13 has symmetrical insertion grooves on both sides of its inner cavity. Sliding connecting plates 15 are symmetrically inserted into both sides of the bottom frame 13 through the insertion grooves. The top of the sliding connecting plate 15 is inserted into the lower surface of the support plate 4. Vibration-enhancing components 6 are symmetrically arranged on the front and rear sides of the inner cavity of the bottom frame 13; Vertical connecting plate 11, the bottom of vertical connecting plate 11 is inserted into the outer surface of bottom frame 13; The rear traction plate 12 is inserted into the back of the vertical connecting plate 11 at its front end. The operator moves the device by pulling the rear traction plate 12.

[0022] The operator holds the rear-mounted traction plate 12 and pushes the device to the location where a pit needs to be dug. The bottom end of the solid drill rod 33 is aligned with the point, and then the torque motor 32 is started to drive the solid drill rod 33 and the spiral blade 34 to rotate at high speed.

[0023] The solid drill rod 33 of the drilling platform component 3 slides down along the outer surface of the vertical connecting plate 11 under the control of the motor 35, passes through the cleaning component 5 to dig a hole in the ground. After digging the hole, the solid drill rod 33 is retracted. At this time, the water stored in the outer drainage box 53 is pressurized into the inner pressurization shell 51. Then, the inner pressurization shell 51 discharges the water through the spray pipe 52 to flush the outer surface of the solid drill rod 33 and the spiral blade 34. As the solid drill rod 33 and the spiral blade 34 slide upward, the soil on the drilling platform component 3 is flushed away. When the water level in the outer drainage box 53 becomes low, water can be replenished to the outer drainage box 53 through the external infusion pipe 54.

[0024] Example 2, please refer to Figures 1-8 The present invention provides a technical solution: based on embodiment 1, the fall arrestor 2 includes: The strip-shaped slide box 23 has symmetrical air drainage grooves on the upper and lower sides of its inner cavity, and its outer surface is slidably connected to the axis of the inner cavity of the vertical connecting plate 11. The height-limiting arc plate 24 has its back end inserted into the front end of the strip-shaped sliding box 23, and the front end of the height-limiting arc plate 24 is evenly provided with drying air holes. The bottom end of the height-limiting arc plate 24 is in contact with the upper surface of the support plate 4. The inner cavity of the height-limiting arc plate 24 is a hollow structure, and both the upper and lower ends of the height-limiting arc plate 24 are reinforced by welding metal plates. The rear pressure control plate 21 is inserted into the back of the outer surface of the vertical connecting plate 11. The front of the rear pressure control plate 21 is uniformly provided with compression push tubes 22. The front end of the compression push tubes 22 is inserted into the back of the strip box 23. After the rear pressure control plate 21 pressurizes the inside of the compression push tubes 22, the compression push tubes 22 extend and push the strip box 23 forward. Then the air duct of the strip box 23 is exposed to the outside of the vertical connecting plate 11, and begins to adsorb air and perform heating. Therefore, the drying air that is finally sprayed out from the front of the height limiting arc plate 24 is heated air. Vibration-enhancing component 6 includes: Hollow guide tube 62, the outer surface of the hollow guide tube 62 is evenly arranged in the inner cavity of the bottom frame 13 through the insertion interface; A solid slide rod 64 has a compression spring 63 sleeved on its outer surface. The top end of the solid slide rod 64 is inserted into the lower surface of the support plate 4, and the bottom end of the solid slide rod 64 is slidably connected to the inner wall of the hollow guide cylinder 62. The variable frequency pump plate 61 has its top connected to the bottom of the hollow guide cylinder 62 via an insertion interface, and the upper surface of the outer shell of the variable frequency pump plate 61 is connected to the lower surface of the bottom frame 13. The variable frequency pump plate 61 can change the pressurization and depressurization of the inner cavity of the hollow guide cylinder 62 by rapidly changing the internal air pump, so that the solid slide rod 64 can perform vertical sliding variable frequency movement, thereby driving the support plate 4 to slide up and down.

[0025] Drilling platform component 3 includes: The upper slide plate 31 has a guide opening in the middle of its inner cavity; The torque motor 32 has its outer surface housing inserted into the upper surface of the upper slide plate 31. A solid drill rod 33 is inserted into the outer surface of the torque motor 32 shaft, and a spiral blade 34 is sleeved on the outer surface of the solid drill rod 33. The outer surface of the torque motor 32 shaft is rotatably connected to the inner cavity of the guide port of the upper slide plate 31.

[0026] Drilling platform component 3 also includes: A long threaded rod 37 is inserted into the outer surface of the rotating shaft of motor 35 to cooperate with motor 35. The bottom end of the guide bottom cylinder 38 and the long threaded rod 37 are rotatably connected to the inner wall of the guide bottom cylinder 38, and a rangefinder is provided in the inner cavity of the guide bottom cylinder 38. The bottom end of the protective cylinder shell 39 is inserted into the upper surface of the support plate 4, the bottom of the guide bottom cylinder 38 is inserted into the bottom of the inner wall of the protective cylinder shell 39, and the top of the motor 35 is engaged with the top of the inner wall of the protective cylinder shell 39. The connector 36 has one side sleeved on the outer surface of the long threaded rod 37, and the other side sleeved on the inner cavity of the upper slide plate 31.

[0027] Connector 36 includes: The horizontal connecting plate 361 extends to the outside of the protective shell 39, and the outer surface of the horizontal connecting plate 361 is slidably connected to the inner cavity of the protective shell 39 through a sliding groove. Anchoring rod 362, the top of anchoring rod 362 is inserted into the end of horizontal connecting plate 361 away from protective shell 39, and the outer surface of anchoring rod 362 is inserted into the inner cavity of upper slide plate 31 through insertion interface.

[0028] Connector 36 also includes: The inner wall of the threaded sleeve 363 is threadedly connected to the outer surface of the long threaded rod 37 through a threaded groove. The inner wall of the adapter collar 364 is sleeved with the middle of the outer surface of the threaded sleeve 363. The lower surface of the adapter collar 364 is evenly provided with photosensitive interfaces. The outer surface of the adapter collar 364 is rotatably connected to the end of the horizontal connecting plate 361 away from the anchoring rod 362 through a rotating groove. The infrared light emitted by the guide bottom cylinder 38 inside the guide bottom cylinder 38 can be received by the photosensitive interface of the upper adapter collar 364, and thus fed back to the mating motor 35. The speed of the mating motor 35 is adjusted according to the distance between the two.

[0029] After the upper slide plate 31 is reset, the rear pressure control plate 21 pushes the strip box 23 forward by pressurizing the compression push tube 22, thereby inserting the height limiting arc plate 24 into the gap between the upper slide plate 31 and the support plate 4. Then, the height limiting arc plate 24 blows air to dry the attached spiral blades 34 through the front air hole. Due to the supporting effect of the height limiting arc plate 24, the entire upper slide plate 31 will not suddenly fall to the ground due to gravity, thus sharing most of the gravity load for the surrounding connecting parts 36, and at the same time eliminating water stains on the outer surface of the spiral blades 34.

[0030] During the retraction of the solid drill rod 33, the variable frequency pump plates 61 located on both sides of the bottom frame 13 drive the solid slide rod 64 to slide up and down by controlling the pressure. This causes the solid slide rod 64 to push the support plate 4 and the drilling platform component 3 to vibrate up and down, shaking off large pieces of soil from the gap between the solid drill rod 33 and the spiral blade 34.

[0031] When the long threaded rod 37 is rotated clockwise by the motor 35, the bottom end of the long threaded rod 37 rotates along the inner wall of the fixed guide cylinder 38. However, when the long threaded rod 37 rotates clockwise, the threaded sleeve 363 fitted on its outer surface will rotate downward along the thread. The threaded sleeve 363 rotates relative to the horizontal connecting plate 361, and will drive the upper slide plate 31 to slide down through the horizontal connecting plate 361 and the anchoring rod 362. This will cause the drilling component composed of the torque motor 32, solid drill rod 33 and spiral blade 34 to slide down and insert into the ground to realize the digging work. During the downward movement of the adapter ring 364, the adapter ring 364 monitors the advance distance by receiving infrared light from the lower guide cylinder 38, so that the upper slide plate 31 stops moving when it is about to approach the outer drainage box 53 to avoid crushing the outer drainage box 53.

[0032] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
